The attacks took place because Osama Bin Laden (the leader of al-Qaeda), who had naïve beliefs about the United States, wanted to punish America the same way he had been punished in the past when the U.S supported the Israelis destroying the towers in Lebanon and killing their people. <u>The 9/11 terrorist attack was considered a huge success for al-Qaeda because it killed and affected many people and damaged the US economy.</u> Al-Qaeda's target was a good choice since the World Trade Center was the heart of New York and its financial district which kept their markets closed for 4 trading days and provoked record losses.
